Another week, another set of free explanations!

Last week, I released explanations to every math problem in The Official Guide. Now, explanations are also available for every problem in The Official Guide for Quantitative Review.

To navigate your way through this fantastic new resource, you can use one of three indexes:

- ...by question number
- ...by difficulty level
- ...by content area

These explanations, as well as the set for OG12, remain available for sale as a PDF booklet. I think you'll find them sufficiently valuable that you'll want to have them at hand even when you're offline, to enhance the value of practicing with the Official Guide books.
